Specification of Letters Patent.

Patented July 2, 191.8.

Application filed October 14, 1915. Serial No. 55,782.

- The objects of my invention are, first to construct a lamp of this type with a minimum number of detachable or. removable parts in as simple and inexpensive manner as possible; second, to provide a hydro-carbon gas lamp with an eflicient removable vaporizer that is capable of rapidly generating the gas'that is expelled into the mixingchamber-through a tip made integral therewith; third, to so construct and protect the jet, that it will be kept free from drafts,

and thedischarge orifice thereof keptclean' and freefromeccumulation of carbon, and, fourth, to so, construct the lamp and; the easing above it that said'lamp can be inclosed within a spherical globe'. These and other 5 objects I accomplish by the means and 'in the manner hereinafter fully described, and a 80 as particularly pointed out in the claims,

' reference being had to the accompanying drawings forming a part hereof, in which-'- Figure 1 is a side elevation of 'my improved burn'er showing the casing and globe Fig. 2 is a transverse section of the globe and easing taken on dotted line 2- 2, Fig. 1.

- Fig. 3 is a side viewof a fragment thereof illustrating the means for retaining the globe in its closed position surrounding the burner, drawn to actual scale.

Fig. 4 is a vertical section-of abroken away portion of the mixing-chamber, the jet and the means for supplying oil-thereto,"

drawn to the actual scale.

. Fig. 5 is a vertical section of the jet taken on. dotted line 5-5, Fig. 4, and -the lower broken away end of the mixing chamber, drawn to a larger scale.

Fig. 6 is a horizontal section taken on dotted line 6-6,'Fig. 4.

Fig. 7 is a detail view of the coupling connecting the feed-pipe and vaporizer. Referring to the drawings, 1 represents a 5 tubular hanger the upper end of which is suitably'screwed into "a suitably shaped con pling-head 2 whose upper end is screwthreaded and adapted to be tapped into the service-pipe (not shown) through which the illuminating or, hydro-carbon fluid is fed from a suitable source, under pressure. This coupling-head 2 is provided with a suitable axial opening 3 which extends down through its upper screw-threaded end into the body 'there'ofa short distance and then extends laterally in alinement with thebore of a laterally projecting stub 4. The bore of stub 4 is engaged by a screw-threaded needlevalve 5 whose outer end has a crossbar so cured thereto the ends of whichv have chains depending therefrom to enable the operator to rock the needle-valve one way or the other. The lateral portion of the passage nearest stub 4 being made greater in diameter to provide a chamber! into which oil or illumin'ating fluid can enter when the spindle of valve 5 is turned in one direction and intowhich it is prevented from flowing when 'saidspindle is turned in the opposite direction. The coupling-head2 is also provided with a vertical passage!) that extends down i from said chamber through av depending I stub "7-, the lower screw-tln'oaded end of. which latter is engaged by the upper end of a wire feed-pipe 8 and is held in gas-tight relation thereto by means of a gland-nut 9. The lower end of hanger 1 is screwed over the upper end of asolid stud 1O projecting upward in axial alinement with the shorter arm of an inverted substantially U-shaped tubular mixing-chamber 11, and the lower end of this hanger 1 is surrounded and inclosed by a suitable sheet-metal casing 12, the upper end portion of which is substantially cone-shaped and its truncated upper end connected in any suitable manner to the tubular hanger. The lower end of this oasing is retained in a concentric position to said hanger by a'transaxial bar 12" through an opening in the center of the. length of which the lower end of said hanger passes. The lower end of casing 12 is flanged outward circumferentially and then downward to form a rim 13 which surrounds the u)- wardly flanged edges of the top openin o a globe 14. One side of this rim 13 as a hingelate 15 secured to the inner surface thereo in any suitable manner and the lower edge of this plate below the edge of the rim is formed into a knuckle in which a strai ht stretch of a 'wire band 16 is journaled. is.

wire band/l6;surrounds the circumferential Q a j 1,270,858

channel resulting from hanging the upper edge of the upper'opening of the globe, and diametrically opposite said hinge-plate 15 its ends are bent outwardly and secured together 'by. a clip 17. One of the ends extends outwardly farther than the other and has its extremity bent into aneye to form a stud 18. When the globe'is closed up into the rim of the casing this stud snaps between the lower-looped ends of a U-shaped spring clasp -19 the upper bend of which latter is lapped over the lower flanged edge of'the' casing and secured thereto by riveting or otherwise,

Feed-pipe 8 extends downthrough a suit-.

able opening in rim 13 of casing 12 into the globe and has its lower end secured in the mouth of the'bore of one of the vertical members of the vU-shap ed coupling 20 by means of a: suitable gland-nut. The oppo- I 20 site vertical member of this U- shaped coupling is provlded with a circumferential flange 21, and above this flange it is screwthreaded and passed through an opening in the lower horizontal arm 22 of 'anL-shaped '25 bracket 23 whose upper end is, preferably, cast in one piece with the lower end of'the' longer arm of the inverted U-shaped mixing Chamberll. This arm 22 is hollowed out underneath, and the adjacent vertical memher of coupling 20passes up into this hollowed out portion, and immediately above said arm the screw-threaded vertical memberhas a nut 24. screwed thereon to clampit-to arm 22. Above the screw-threaded portion upon which this nut is screwed the vertical member of the coupling is still further reduced in diameter and screw-threaded. 1

The bore of the coupling from the-end there-- of to which feed-pipe 8 is attached, to the 40 base of the opposite vertical member, is, preferably, the same in diameter, but the bore of this last mentionedvertical member is considerably reduced in diameter and the upper end is made funnel-shaped and engaged by the cone-shaped head25 ofa' vav porizcr 26. a

This vaporizer consists of a wire plpe that extends vertically upward from the coupling a short distance and is then bent 60 laterally in an inclined direction toward the mixing-chamber 11. Approximately in the same horizontal plane with,the top of the 'burner or mantle 27 ,.that is secured to the end of the shorter arm of the mixing-chamber, this vaporizer-pipe 26 is bent partly around't he intake or shorter arm of the mixing-chamber,'-and then it extends downwardly slightly below the end of the longer member of the mixlng-chalnber, and is then bent horizontally and transaxially across the mouth or intake end of said longer arm.

The portion of the vaporizer-pipe passing under the lon erarnr of the mix ng-chamber 1s flattenec andata point in alinement at; with the axis of said longe'r'arm it is pro-y gland-nut 31.

A vertical rod 32} extends axially up through this member-29, and its upper portion within the reduced upper portion of said member is increased in diameter; and

at its upper extremity it is provided with an axially extending needle 33, that enter'sand is adapted to have vertical play in the orifice of jet 28. The bore of the lower larger por tion of tubularmember 29 is likewise increased and packing 3a is .placed within the a same which 1s engaged by a sleeve 35 su'r- J rounding rod 32.and compressedby tightening land-nut 31. This rod. extends down a suitiihle' distancebelowithe gland-nut and is shaped so as to afford a finger grasp to enable it-to be reciprocated so that needle 33 can clean out and set free any accumulation of carbon in "theorifice of the jet.

.The lower end'of the longer branch of the inverted U shapecl mixing-chamber has'a res. movable tubular extension 37 depending, therefrom, which is, preferably, made of" k sheet metal bent so that its side edges form" a longitudinal seam which is next bracket j 23. The lower end ofeXte nsion-37 is bent sidewise under the horizontal :arm of the bracket a short distance, and at the inner curve of this bend the edges ofjthe lon itudi-' nal seam thereof are provided with ips 38 105,;

that lap against and embrace a longitudinal fin 39 of bracket 23 between them and are p I secured thereto by a transverse pin 40 or its 1 equivalent... The outercurv of the bent lower end of extensionz'37 is provided with 1 alongitudinal slot 41 to permit Of tl16 passage of the lower portion of rod 32, and the upper edges of the extension are recessed filth pointsdiametrically opposite each other for i the passage of the lower flattened portion 1101 of the vaporizer-pipe, which latter is extended therethrough and its eXtremityclOSed and provided with 'a lateral finger 42 that enters and is caught in a hole 43 in fin 39 of bracket 23.. Extension 37 is for thepurpose of preventing either transverse or verti'cal drafts of air affecting the jet, and thus '7 effecting the steady'discharge of gas therefrom, and an even steady glow of the mantle during the operation of the lamp.

In operation, valve 5 is manipulated to a permit the oil to pass into and through pipe 8 and-thenthrough coupling 20 into vapor-j izer-pipe, 26. The oil is forced through filtering material 44 in this vaporizing-pipe to the jet and the application of a lighted match to the mantle vaporizes the oil in said vaporizer-pipe and simultaneously ignites said vapors as they pass through the mantle and causes the latter to become incandescent, in which condition said mantle radiates heat and continues to vaporize the oil in the vaporizer-pipe so long as the oil flows therethrough. Should carbon form in the orifice of the jet and obstruct the discharge of gas therefrom it can be dislodged and pushed out simply by reciprocating rod 32.

What I claim as new is:

1. In a hydro-carbon lamp comprising a mixing-chamber, a burner, a feed pipe leading to the mixing-chamber, a vaporizer extending transversely across the mixingchainber, an aperture in the vaporizer, a rod arranged to enter the aperture; said rod extending from the transverse portion of the vaporizer, and a tubular extension hav- 1 ing a lateral (projection; said extension surrounding sai the transverse portion of the vaporizer, and said rod having a construction which permits of its being reoiprocated Within the tubular projection.
